Introduction

OpenOCD mainline includes preliminary support for Cortex-A9 and Pandaboard. See the Compiling_OpenOCD for instructions to checkout and build from source, or visit OpenOCD homepage.
For using this solution, you need at least:
- a usb jtag dongle,
- an openocd excutable running on a host machine,
- a gdb cross compile for arm platform.

JTAG Hardware HowTos

Known Issues

Memory Access

All memory accesses (including md/mw commands and disassembly) execute through the debug AHB on the L3 interconnect; resources on the L2 interconnect currently can not be accessed. This includes ROM, local PRCM, and anything in the Cortex-A9 "private memory region" (snoop-control unit, global interrupt controller, timers and watchdogs).

SMP Support

debugging A9 cores simultaneously is currrently not supported

Debug clocking

The debugger may not be able to access the A9 processor cores due to an issue with omap4430 clocking. If your debugger can identify JTAG devices, e.g.:
